Just finished it this day, folks; was waiting for that voltmeter from eBay to come. This is no big deal - just a potentiometer, two resistors, some wiring and desoldering work, and it's done. No active components at all with this hack - no external ICs nor regulators and all that stuff.
I have tested the voltage drop on load, too. Doesn't matter whether the load is 1A or 10A, the drop is no more than 0.15-0.2V than the nominal voltage.
And yep, no big heatsinks, just original circuitry that can be found in an ordinary ATX supply.
So, enough talk, watch and see for yourself folks. Tell me what you think afterwards. And then, go back to your heater elements you dare to call "LM 317 voltage regulators", not mentioning calling that a "lab supply" (combined with a large heatsink
)
//And yes, its short circuit proof!
